Dask Distributed Diagnostic Webpage not working

Question

I've gotten dask up and running on my cluster, but I can't seem to access the diagnostic webpage. The landing page is visible, see below:

But all the links just hang and never load the page.

The scheduler started fine with this output:

[hoffmand@h05u06 ~]$ dask-scheduler --scheduler-file dask-scheduler.json

Answer 1

I just experienced the same issue, and apparently, with bokeh <= 0.12.5 and tornado = 4.5 (see https://github.com/dask/distributed/issues/1027)

So either:

• Downgrade your tornado to 4.4.3
• Upgrade bokeh to 0.12.7 (or at least 0.12.6 apparently)

I just upgraded to bokeh 0.12.7 and it works like a charm.
